Application filed march 3, 1921. Serial No. 449,579.

To aZZ whom it may concern:

Be it known that I, HENRY G. JOHNSON, a citizen of the United States,residing at East Hampton, in the county of Middlesex and State ofConnecticut, have invented new and useful Improvements in UniversalWinder Heads, of which the following is a specification. This invent-ionrelates to machines for winding thread on spools, and hasparticularreference to means somewhat in the nature of an attachment towhat are known as universal winders, whereby a spool or tube having ahead at but one end can be wound with the thread in layers.

The object of the invention is to provide means which will so lay thewound thread that the surface of the layers at the end of the spool ortube having no head will be tapered or beveled, whereby the thread isunlikely to fall off at that end, and the thread can be freely drawnfrom that end without encountering any spool head.

The object mentioned is accomplished by automatically efi'ectlng agradual longitudinal shifting of the rotating spool, and the traverse ofthe thread guide or eye relatively to each other. In the illustratedembodiment of the invention, the thread guide, during operation, has atraverse of a given length, so that the number of coils in allthe layersare always the same for a given length of spool or tube. As the layersof thread are superposed one upon the other, the thread guide ispushedaway from the axis of the spool, by the increasing diameter of thewindings, and this movement of the guide is utilized to gradually shiftthe relative positions of the spool and the traversing thread guide inthe direction of the axis of the spool. In the machine illustrated. itis the spool which moves longitudinally.

With the above object in view, the invention consists in the mechanismsubstantially as hereinafter described and pointed out in the claims.

Of the accompanying drawings forming a part of this specification,-

Figure 1 is an elevation of the machine, omitting such parts as are wellknown in this type of mechanism.

Figure 2 is a top or plan view of the same, omitting the traversing camwhich appears in Figure 1.

2 of a rod 'or bar I) mounted to slide in a guideway of the swingingsupport 7. One face of the thread guide is beveled, as at 3,

to substantially correspond with the angle of the face of the head 4 ofthe spool 5. This bevelingof the guide 3 is to enable the thread, whichruns through the notch or eye 3", to be laid close to the spool head 4(Figures 6, 7, and 8). The support 7 is pivotally mounted on the j aekshaft 8, by means of arms 7 of the said support, and suitablecounterb-alancing devices, such as are usually employed in this type ofwinder, may be employed to exert a tendency to press the guide 1 towardthe spool.

Secured to the member 7 is a plate 9 having an upstanding pin 10 onwhich a block the parts when the spool is 11 is mounted. Slidablyfitting a transverse the two arms 12 and 16 practically constituting anelbow lever. A fitting 17 is adjustably secured on the arm 16 by a setscrew 18, and has a vertical pin 19. 20 connects the pin 19 with afitting 21, secured by a set screw 22 to a slide rod 23, mounted toreciprocate, but not rotate, in bearing ears 24 of a bracket 24 rigidlysupported on short arms 25 by clamp clips 25*. The arms 25 frame of themachine by screws 27.

Rotatably mounted on the outer end of. the ,rod 23, is an externallythreaded sleeve 28, held between collars 29, secured to the rod by setscrews 30, said sleeve having a knurled. portion 31 for convenience inro-- tating it. Mounted on and engaging the threads of the sleeve 28 isthe internally threaded hub 32 of an arm 33, forked at its outer end andengaging an annulangroove A link are secured in ears 26 of the 34 in thespool mandrel 35. The mandrel is slidably mounted on the extendedportions 36 of the main shaft 37, the driving connectionbetween saidshaft portion and the mandrel being maintained by a key 38 and key-Way39 (Figure 3).

A belt pulley 40 mounted on the shaft 37 is adapted to be connectedthereto to drive it by a suitable clutch mechanism, not necessary toillustrate, the engaging operation of the clutch being effected manuallyby a clutch lever 41 at one end of a clutch-operating shaft 42. Thethrowing off of the clutch is usually effected automatically, bymechanism not necessary to illustrate, as it forms no part of thisinvention.

The shaft 37 also carries a pulley 43, connected by a belt 44, with apulley 45 which, through suitable speed-reducing gearing in the casing46, drives'the jack shaft 8 carrying the path cam 47. Said cam 47engages a roll carried by a pin 48, which projects down from the slideIn operation, an empty spool is secured upon the mandrel by the taperedplug 49 acting in the usual way to expand the split portions of themandrel, and at the start of the winding the thread guide 1 bearsagainst the spool about as indicated by the full lines in Figure 6, thisbeing effected by the usual counterbalancing mechanism, not necessary toillustrate herein. During winding of the first layer the cam 47 effectsa traverse of the slide 5, and its arm 2', to the position indicated inFigure 1, carrying the guide 1 to about the position indicated by dottedlines in Figure 6. As the return layer is being woundthe guide 1 bearson and rides'along the first layer, resulting in swinging the arm 2 andthe support 7 back. The plate 9 and its pin 10, carried by the swingingsupport, transmits this motion through the elbow lever 12, 16, to thelink 20, and through the latter to the slide rod 23 and the fork'arm 33,which latter effects a slight longitudinal movement of the mandrel and Ispool toward the right (Figure 2), or toward the outer end of the shaft36. The parts are so proportioned that this longitudinal movement of thespool equals the diameter of the thread being Wound. As the windingprogresses the thread guide is pushed farther and farther away from theaxis of the spool, and the spool is shifted more and more to the rightas shown by comparing Figures 6, 7, and 8, thus presenting a filledspool having the exposed end tapered or beveled.

Preferably the angle of the bevel is at 45 to the axis of the spool,corresponding with a similar angle of the inner face of the one spoolhead 4.

To secure the best results it is, of course, essential that the threadfilling shall, be compact. To this end it is important that the .partsof the machine are so proportioned and commodate spools having heads 4of different thickness.
